To all 'whom t may concern.'

Be it known that we, MARTIN O. Rnriruss and JOHN GEORGE RnHFUss, bothcitizens of the United States, and residents of Philadelphia, in thecounty of Philadelphia and State of Pennsylvania, have jointly inventeda certain new and useful` Vlrapping-Ma-A chine, of which the followingis a specification.

The principal object ofthe present inveng tion is to provide a rapid,reliable and labor saving machine for automatically Wrapping groups orpiles of magazines, publications or the like, with paper and securingthem into bundles or pack'ages with reliably flastened string or twine.

Other objects of the invention will' appear from the followingdescription.

The invention will be hereinafter described and finally claimed, but itmay be said that the invention is embodied in a machine comprising incombination the fol lowing instrumentalities or some of them: a carrierfor feeding the piles of magazines or the like to the machine; a paperroll and feed therefor; a movable table for receiving first the paperand then the pile; paperv cutting mechanism, folders for.` wrapping thepaper about the pile, a presser for temporarily holding the folded paperin place, a clamping device, means for shifting the table to transferthe wrapped pile. to the clamping device, cord winding mechanism, meansfor turning the clamping device and pile ninety degrees to permit of thewinding of` thereord in both directions, and a cord fastening andcutting device.

' In the' accompanying drawings is illustrated one embodiment of amachine embodying features of the invention.

ln the drawings,Figure 1, is a general plan view of Vthe machine, inwhich the various functions are indicated in a more or less general Way,to be more fully shown in individual detail figures.

It is believed that, the invention can be best described by firstreferring to the principal parts of the machine and stating what theyIdo, and then explaining in detail the various features of construction,and that course will be followed.

Referring tothe general view, Fig. 1, the piles m each consisting of anumber of books, publications or the like, are placed at intervals uponthe liXed slide A, and the Wrapping paper y placed in the grippers ofthe paper feed mechanism B. Paper is carried by an intermittent motionin the direction `of the arrows,'ove'r the movable slotted table andfolder mechanism E E wraps the paper about the pile and a presser foot Fdescends and holds it in place. rllhe folders are then retracted, andthe table carrying the wrapped pile and thepresser foot which holds, ismoved to the .leftinto position in clamp Gr. rlhis clamp is nowoperated,securely holding the package during the winding operav tion,presserF isreleased., andfwith table C returned to their former positionto receive succeeding piles and repeat operations. Clamping device (inowby a partial rotation turns the package ninety degrees into positionshown in Fig. 2,` and cord Winder lil, by describing .a proper path,puts a turn of cord once around the package. rlNhe clamping device turnsto its former position and the cord Winder operates again to puta turnof cord about the package, which is therefore now wound in bothdirections, and the cord Winder holds both ends of cord crossed on topof package. Fastening device K now operates` making a clip from a wireand its arm descending upon the crossed cords and places over theirintersection the previously made wire clip which holds them securely,thereafter cutting the cord. rlhe Winder releases its cord end, andclamping device is released,

f acting with star-wheel 26, which through gears 27 gives anintermittent vmotion to the hollow shaft 28 which operates thev cordwinding mechanism H. Bevel gears 29 transmit power from main shaft 20 toa shaft 30, placed at an angle of 45, which operates the making andplacing ofthe wlre clips for fastening the cord, after wlnd- 1n T-Iavingthus described the general operation of the machine' and method ofdriving, a further explanation of the construction by which the variousmovements are obtained will be given.

Having regardto Fig. l, and referring more especially to Fig. 3, A isthe fixed slide way upon which the piles of magazines or otherI matterare deposited. 40 are endless 'chain carriers provided with fingers 41,ap propria-tely spaced, for engaging therear of the piles on either sideof the slide-way and carrying them toward the machine table until thepile is, by dropping, deposited on the movable slide 42 beyond thecross-cleat 43,

thereon. Carriers 40 are driven by'meansr of chain 44, shaft 45 andcounter-shaft 46 from shaft 24 by means of bevel gears as shown. Movableslidel 42 is supported in ways on fixed slide A and is reciprocatedbylinksl and levers 47 actuated by a cam 48 on shaft 45. Wrapping paper y,is caught in one of the spring closed grippers carried by Ithe paperfeed chain 56, as hereinafterdescribed, and is drawn over the movable`slotted table U to receive and underlie the pile to be wrapped. The pile.having been moved onto slide 42, cam 48 is so timed as to carry thisslide forward at once, away' from fingers 41. until the pile is directlyover table C. with the Wrapping paper between. At this instant strippers50, carried from a slide 51 are projected upward kbehind the pile bvmeans of spring actuated .lever 52. Cam 48 continuing its rotation,

withdraws slide 42, leaving the pile upon the paper on table C andstrippers 50 descend at once out of action by means' of cam 53 acting onlever 52. During this operation the above mentioned paper gripper. 55,shown in dotted lines in Fig. 3, has moved forward to a position to beacted upon by spring and cam actuated lever 57, whose cam 58 now acts toopen said gripper and down of the ends of the differences in release thepaper. By this time a second paper gripper 55, so spaced on the carrieras to be in line with its actuating rod 59, and shown in full lines,has-been snapped shut gripping the paper behind the line of cutters D.Rod 59 which is slotted midway and slides on a projection 60, isactuatedby lever 61, carrying a roller which co-acts with a cam 62 on shaft 24.

Wrapping paper y is fed in the following manner, see Fig. 8: Bevel gears5l transmit motion from the constantly rotating shaft 24 to a roller andstar-wheel device 52, which is connected by gearing 53 with the drivingsprocket of chain 56. lBy this means chain 56 carrying the papergrippers 55 is, moved periodically to bring each gripper in turn fromthe line of its rear actuating rod 59 to the line of the front actuatinglever 57 see F1g.'1. j @As soon as the rear gripper grasps the paper, acam 63 on shaft 24, see Fig. 9, actuates the spring pressed rods 64raising the movable shear of cutters Dland cuts off the paper. Thefolders E have during this tlme been lying out of action as shown indtotted lines in Fig. 5. As soon as the paper has been cut off and thefront grippers have been opened, cams 66 on shaft24 act to raise slides67 and thereby swing the folders up into the vertical position, foldingthe paper about the pile. Spring pressed rollers 68 at the ends of thefolders insure the folding paper on top of the pile, and allow forslight variations in the height'of the piles caused, for example, bythickness of books or changes 1n the number of books. The piles areapproxlm'ately of agiven height, and these rollers68 are adjustedaccordingly by slotandbolt'connections 69 to the folders. Cams 66 aresimilarv and placed one slightly ahead of the other so that the foldersmay not act at exactly the same time, thereby preventing the ends of thepaper as they fold in from interfering with each other. Presser arm F 1snow actuated by bell crank lever 70, hook arm 71, and cam 72 on shaft20. By this means presser F is brought down firmly upon the lapped endsof the paper on top of the pile, and the folders E are withdrawn out ofaction by the cams 66. Table C is now moved to shift the wrapped pile to-the clamping device or chuck G, as follows: On shaft 24 is an arm 75,shown in dotted lines in Fig. 4, carrying a roller which actuates astar-wheel 76, which by means of gearing 77, is arranged to give a crankarm 78 a half revolution. This crank arm carries a roller which slidesin a slot in a lever 79, pivoted to the base plate 80 of the machine,and connected at its upper end by a short link with table C. This halfrevolution of crank 78 from the position shown in full lines to thatshown in dotted lines, Fig. 3, moves table C to a position where thecenter of the wrapped 95 from the table 95 of the machine and has theholder, so that i iaaaaaa pile thereon is directly over the turningcenter of the clamping device G. This device, see F ig. 6, comprises aturnable member 81 carrying a sliding jaw 82, which at this stage of theoperation is retracted downwardly out of action. J aw 82 is carried on ahollow post mounted on a stud 83 with a pin and slot connection, andnormally upheld therefrom by a spring 8d. This allows not only forslight variations in the height of the package, but also for packages.of substantially diderent heights, similar to the adjustment allowed foron the folder rollers. The movable jaw 82 is now moved upward to clampthe package by means of bell crank lever 85 operated by cam 86 on shaft20. Cam 72 now acts to raise thelong arm of bell crank lever 70, therebyraising pressure arm- F and table C is returned to its initial positionby crank 78 making anotherl half stroke due to star-wheel 7 6 and roller7 5. The paper feed at once operatesto draw another length of paper overthe table on which is deposited another pile from slide A, and the cycleof operations is repeated. Meanwhile' the package' we have beendescribing was lett by the removal of table C held in clamping device(nl. This clamp is shaped to cover alittle less than one-quarter thearea of the package in order to allow of the winding operation tofollow. ln order to more fully support the package a rail 87 is broughtup into action by means of a cam 88, just before the' table was movedaway. 87 is a fixed rail placed at the height of jaw 82 when open forsupporting the end 'f the pile when table is retracted, slots beingprovided in the table for the projection of said rails therethrough.There are also support ing bars 89 and 9,0 actuated byl cams 91 and 92to support the overhanging portions of the package on eitherside ofclampingdevice G. At this time, bar is retracted by cam 92, clampisturned 90O into, position shown in Fig. 2, by cam 93 and bell cranksegment, and pinion 94, and bar 89 is eX- tended under the ile, as shownin Fig. 2. Supporting rail 87 is now lowered out of action while WinderH wraps a length of the cord m once' around the package crosswise, bymeans hereafter to be described. Clamp now turns to its voriginalposition carrying the package still clamped in its jaws, supporting bar89 being retracted and bar 90 again projected out under. the pile. llnthis position Winder H puts the cord agaln around the package, this timein its lengthwise direction, rail 87 being momentarily lowered by itscam 88 out the way of Winder H at each revolution thereof. The Winder isoperated in the following manner: Ade'scription has been given of theshaft 28, revolved intermittently by star-wheel 2,6. This shaft iscarried n bearings supported on its inner end an arm 96 to which ispivoted the cord windingarm 97. Shaft 28 is hollow and has slidablelengthwise within it the shaft-98 on a feather 99. Shaft 98 carries onits inner end an armi 100 which makes slot and pin connection with anend of the cord winding arm 97. The cord m is threaded lengthwisethrough a hole running through shaft 98, to the inner end thereof, overpulley 101, led at right angles out to a pulley 102 on the winding armand thence led through the length of the long arm of 97 and, deliveredthrough. a hole at the end thereof. llt will be readily seen that ytheintermittent revolution of shaft 28 periodically revolves winding arm 97about the axis of said shaft. The projecting end of the cord beingcaught fast in holder 110, to be hereinafter described, this revolutionof arm 97, draws in the cord m and lays it around the package, cam 108,on shaft 98 acting through the slot and pin connection of arm l100 :withwinding'arm 97 to make thev cord delivery. end thereof follow therectangular path necessary in circumscribing the package. Each time thewinding arm makes a revolution, arm of holder, H has to be momentarilymoved out of its path,.which is accomplished as follows: Arm 110 ismounted in a slide 111 carried above one of the bearing brackets of.shaft 28, see Figs. 8 and 10. This slide is actuated byl a cam 112, onshaft 28, so that at the required instant arm 110 is advanced forwardbeyond the path of the cord carrying a-rm allowing said arm to pass andcomplete its revolution.

The end of cord m projecting from the end of arm 97 is originallythreaded through a hole in the end of holding arm 110 and held thereinby a small clamping lever 113 operated by a spring 1111 on rod 115. Whenit is desired to drop the end of the cord at the' end of the winding andfastening operation, p

clamping bar 113 is opened by means of a, cam 116 on main shaft 20acting through ica bell cranks and. link 117 upon the free end of rod115. After the `first winding of cord has been put around the packages,when it is turned 9.0o by the clamping mechanism, itis necessary'toraise holding arm 110 slightly above the package to clear the cord. .Tothis end arm 110 is not mounted rigidly on the slide 111, but by meansof a pin or stud 118, which stud passes downwardly'through said slideand is capable of vertical movement. A spring 119 normally holds saidstud and cord holding arm in lowest'position, but at the time it isnecessary to raise to clear cord, a.

cam 120, see Fig. 10, actuates bell crank and \link121 to raise the freeend of a lever 122, which lies directly below the stud 118. The free endof this lever has furthermore a side projection 122 thereon, to allowfor the above described slidi movement given to 118 may not pass od'holder arm lies to one side of the center of the package, but afterevery package is finished od in the machine and cord is cut,

Athe end left projecting from the hole in end of winding arm must bethreadedinto the hole in end of holder arm as hereinafter to bedescribed. To this end holder arm must be turned on its supporting post118 to bring its free end over center of package against the end ofwinding arm 97. This result is obtained by an arm 123 fastened to thesupporting stud 118 of the holder arm, by a set screw and keyway whichallows said stud to have its free vertical movement. Arm 123 is actuatedat the proper moment by a cam 124 on shaft 20 acting through lever 125.As shown, cams 120 and 124 are combined on the same drum. Having now puttwo laps of cord about the package at right angles to each other, anddrawn the ends slightly apart on either side of the crossing, there arethen three strandsv of cord to be fastened ed, which is done by placinga wire clip rmly and tightly about them. F or the details of thisfastening device K, see Figs.' 11, 12, 13 and 14, together with Fig. 1.

On the table 95 of the machine is secured a stand 130 with anoverhanging arm carrying a head 131 directly above the center of thepackage as it finally rests ready bound in the clampingmechanism Gr.Stand 130 carries reel 132 of wire 'w forforming the cord fastening 'orclip. The wire is fed by feed rolls 133, connected by gears 134, whichreceive'motion from shaft 30. by bevel gears 135 and 135 and verticalshaft 136. One of these feed rolls, the upper one as shown in Fig. 11,has no-t a complete peripheral-bearing on the wire, the section whichdoes coact with the lower roll being made to feed the wire at just theproper time and just the proper amount. As shown in Fig. 13, the wire isfed into thebeveled `opening of a hole through a block 137 secured tothe head 131.

Movable vertically in head 131 is a slide V138 carrying on its rearyface a rack 139. Slide 138 carries ways for a secondary slide 140 whichhas on its rear face a rack 141 arranged to one side of rack 139. Slide138 carries the pivot joint of a pair of arms 143 which actuate saidnippers. Slides 138 and l 140 'areactuated by their racks 139 and 141engaging the toothed quadrants 144'and 145 mounted on concentric shaftscarried in bearings on the rear of stand 130. Quadrant 145 is mounted on'the hollow shaft 146 which carries at its opposite end arm 147 actuatedby rod and lever 148 from a cam. 149 on shaft 30. Quadrant 144 isLicence mounted on shaft 150 which passes through shaft 146 as a bearingand carries on its opposite end arm 151. Arm 151 is actuated in asimilar manner to arm 147 by means of rod and lever 152 from a cam' 153,which as shown is made on the same disk with cam 149.

154 and 155 are slides which carry on their forward ends" respectively aformer and a gripper for wire w. These slides move the v former andgripper into and out of. action at desired times by means of cams 156,rods and levers 157, and levers 158 and 159 on shafts 160 carried inbearings on the. stand 130.

So long as the cams 149 and 153 move the vertical slides 138 and 140exactly together there will be no opening or closing of the nippers.Said nippers are shown in Fig. 13, as in their uppermost position, andas seen theiry bottom line comes exactly at the level of the center ofthe wire. rlihese ends are in fact grooved to receive the upper halfsection of wire and the groove in the left hand nipper member terminatesabruptly midway as at 161 forming a stop for the advancing wire as fedthrough the block 137.

At the time the wire is fed in, slide 154 is in its forward position andthe former on its end helps to support the wire end and hold it againststop 161. Slide 155 then moves into its forward position, shown in Fig.14, the serrations on its face sliding over the wire and being slightlybeveled hold it down against the former. Cams 149 and 153 now act tobring slides 138 and 140 downwardly in unison. The right hand jaw of thenippers is slotted as at 162 to allow it to pass block 137 and form acutting edge therewith. So the downward movement of the nippers cuts odthe wire flush with the face of the block and the further movement bendsthe ends of the short piece of wire downwardly overl` the former and aslight acceleration being given to slide 140 by its cam, the nippers arepartly closed, the rounded out notches 163 therein pressing the wireinto the staple form shown in Fig. 13. The slides 154 and 155 are nowwithdrawn backwardly .by their cams, and slides 138 and 140 descend inunison carrying the wire staple in the notches of the nipper jaws untilsaid jaws reach the level of the top of the wrapped and bound package,indicated in F ig. 11. At this point, slide 140 is again accelerated byits cam, which closes the nipper jaws and presses the wire staple, whichstraddles the three strands of cord, into a ring form, clamping saidstrands firmly together. As seen in Fig. 1, the overhanging arm of stand130 stands at an angle to the line of the package, and the descendingslides and nippers place the wire staple catercornered over tl. sintersection of the cord strands, insuring that it does not foul them.Also Fig. 1 shows that wire w is delivered by` feed rolls' 133 at' aslight angle to the line of the overhanging of stand 130. Thisslightangle is maintained'by the hole g in block 137, and it is just suihcientto provide the passage of the ends of the wire staple by each other inthe formation of the ring or clip, allowing a tight clampv upon thecord.

.mounted on the nipper jaws. Before the final clamping movement of thesejaws is completed the cord winding arm??7 is raised slightly by theaction'of a lever 166, see 6, actuated by a roller on its other endextending in the path of a cam-like projection on the revolving disk. itthe proper point cam 103 is cut away as at' 103 for its pin to slip inand allow of the endwise arm 97 rlhis brings the cord carried thereby inbetween the cutting members, and the final clamping movement of thejawscuts off thev cord vbetween. the'wire clip and the to receive theend of the cord projectingfrom the winding arm. 165 are guards on eitherside of the nippers 14:2, insuring that during the formation of the wirestaple the nipper jawsfollow the described path with nicety. As theslides 138 and140 raise the nippers after this iinal cutting andclamping operation, the cycle of operation of the machine on the packageis finished, and jaw 82 of the clamping device Gr` is opened by ,cam 86,and rail 87 is lowered by its cam to keep the package level, allowing itto rest freely until it is bodily pushed out of the machine by thesucceedingwrapped pile b@- ing carried to the yclamp by table C. A chuteor conveyer may be provided to receive the ejected packages.

It will-.be obvious to those skilled in the art that modifications'maybe made in details of construction and arrangement without departingfrom the spirit ofthe invention; hence we do not desire -to limit thelatter further thanA the prior state of the t@ art and the appendedclaims may require.
